Postmodernity's Musical Pasts considers music after 1945 as a representation of concepts such as "historicity" and "temporality". The volume understands postmodernity as a period in which both modernism and postmodernism co-exist. It is attracted to a wider interpretation of "historicity" that focuses on the complex nexus of past-present-future. "Historicity" is understood as leaning closely on "temporality", generally thought of as the linear progression of past, present and future. The volume broadens the absolutist understanding of temporality to include processes which can occur in circular, spiral, transcending and other formations. The book covers an extensive spectrum of topics from classical to popular and neo-traditional musics to concerns of the disciplines of musicology. Such a wide range of topics from both the centre and the periphery of the musicological canon mirrors the eclectic and diverse nature of the postwar era itself. The first section investigates how to understand manifestations of the past in musical composition with regard to time, on the one hand, and with regard to genre, style and idiom, on the other. A second section shows how time and history manifest themselves in art music. A third section takes the contrasts and transitional moments of post-1945 practices further by looking at the temporality of reception from different angles. A final part investigates questions of nostalgia and temporalities of belonging.

This book highlights the acoustical metamaterials’ capability to manipulate the direction of sound propagation in solids which in turn control the scattering, diffraction and refraction, the three basic mechanisms of sound propagation in solids. This gives rise to several novel theories and applications and hence the name new acoustics. As an introduction, the book mentions that symmetry of acoustic fields is the theoretical framework of acoustical metamaterials. This is then followed by describing that acoustical metamaterials began with locally resonant sonic materials which ushered in the concept of negative acoustic parameters such as mass density and bulk modulus. This complies with form invariance of the acoustic equation of motion which again exemplifies the symmetry property of acoustic fields.
